is provided with the usual lid 6.

Longitudinally' slidable into and out of the box- 1'is an upper'bearingunember' 7 which '-at its rear side, in its operative; position,-

bears against the box 1.' The-member 7 is disposed above the-groove Sandis spaced apart from the journal. lo hold the memher 7 from any turning movementysuitable means may be provided, such as longitudinal tongues 8 respectively fitted in longitudinal A grooves-9 in the box 1,-Figs.- 1 and 5.

Below the upperbearing. member/7 "is; a

front lower-bearing member 10 andat the rear thereof a lower rear bearmg member 11,

Fig-J1. 'The inner sides ofthemembers lO arc'uate and form with the grooved; portion of the journal 2 and-with each other an annular-ball race in which are located "longitudinal rollers 12, disposed betweenthe abutments 4: and 5, and which areadapted for traveling contact with the journal 2 and i with the-members 7 10 and 11.

The front portion of the member-:T has rollers '12 to limit their forward movement with respect to the member 7. 'The inner periphery of the'member llis provided with a similar ledge 14 adapted to f engage "the and "11 bear against the-box 1. The inner peripheries of the'members 7, 10 and llare an inner 'arcuate ledge 1,3,Fig. 1,which is adapted to engage the front ends of the a I u -1n the position occupied-by it when it'is beother ends of the rollers12. The front side of the-member? has a lug 15, provided with one or more vertical holes 16, which may be engaged by a suitable instrument, not shown, for sliding the member 7 toward and from its operative position.

For releasably holding the'lower portions of the members 10 and 11 from forward movement, suitable releasable locking means may be provided. For this purpose, there may be provided two T-shaped locking'members 17, which are alike in'construction, one being shown in "Fig. '12, The locxing memhere 17 are respectively mounted in 'verti cal holes provided in two lugs 18 on the inside of the bottom of the box 1. Each member 17 is provided with a transverse hole 1.9, which is'adapted; to register with a transverse hole 20, with which each lug 18 is provided. Two pins 21 are removably mounted in the holes 19 and in the lugs 18 for releasably holding the members 17' in their locking position, in which the heads of the locking members 17 respectively bear against the'front sidesof' the membersjlO and 11. For holding the upper portion ofthe rear member 11 in its operative position,

the inner side of the box ,1 is provided at opposite sides respectively with two lugs 22, which extend across the front side of the member 11. WVhen the latter is inserted in the box, it is tiltedupwardly and rearwardly, as shown in solid lines in Fig. 10, and in this position is passed behind the lugs 22 and then upwardly and rearwardly, so as to' assume theposition shown in dotted lines in Fig. 10. To permit of this movement, the inner side ofthe rear of'the box may be recessed at 23, Fig. 10.v

For holding the upper portion of the.

front member 10 in position, and for also holding the upper member 7 in its operative position, suitable means may be provided, such as two locking members 24 and 25, each of which has one or more forwardlyextending'arms 26, which are provided with vertical holes 27 ,in which are removably mounted vertical pins 28, which extend respectively through vertical holes provided in two lugs 29, which are respectively (118- posed on opposite inner sides of the box 1;

The lugs 29 are each provided with recesses adapted to respectively receive the adjacent arms 26. lVires 30 may be extended through holes provided therefor in the pins 2l'and 28 to hold the latter from detachment. 7 I 1 My im roved dust guard comprises an up per mem er 31, Fig. 2, and a lowermember 32, which are slid ably fitted'in the usual grooved portion 33, in the rear portion of thebox 1. The lower edge of the member 31 has an arcuate recess in which is fitted an" arcuate lining 3 1, preferably of' yielding material, such as felt.' The upper side of the spirit of my invention.

the member .32 has an arcuate portion in which is fitted a similar lining 35, which is also fitted in the lower portion of the groove 33. The lining 31 and 35 bears on the periphery of thejourn al 2 andprevents lubricant from being splashed outof the rear end of the box along the journal.

In assemblingthe bearing, the dust guard members 31 and 32 are slipped into the groove 33. The member 11 is then inserted, as shown in Fig. 10, to the position shown in dotted lines in said figure, following which the rear locking member 17 is in I serted in the rear lug 18, and is locked inposition by the insertion of the rear pin 21, a wire 30 being passed through the pin to hold it in position.

The journal 2 is then passed through the dust guard and member 11. The member 10 is then inount-ed in operative position,

lFigs'. 1 and 4, after which the locking mem-- berl'? is placed in the front lug 18 against the front side of the member 10. The front pin'21 is then'passed through the adjacentmember 17 and front lug 18, and a wire 30 passed through the'pin.

The rollers 12 are then pla'ced'one byone between the journal and the members '10 and 11.- When the rollers have all been placed, the member 7 is slid rearwardly into its operatlve position, Figs. 1, 4: and 5, after which the locking members 2 1 and 25 are respectively interlocked with the lugs 29. The pins 28 are then extended through the lugs 29 and the adjacent locking members 24 and 25 respectively. -Wires30 are then passed through the pins28. The bearing members7, 10 and 11 will now be locked securelyin their operative positions.

WVhen the member? requires to be removed, for any purpose, the operation just described is reversed.

The arcuate ledges 13 and 14being adapted to respectively engage opposite ends of the rollers 12, the latterare limited as to longitudinal movement relatively to" the bearing members 7 10 and 11. I

I do not limit my invention to-the struc-' said journal an annular race and bearing at their rear sides against saidbox, removable locking members bearing respectively against the front sides of said members for holding the latter in operative position and respectively engaging said lugs, releasable means for locking said locking members to arcuate inner surfaces adapted to form with said lugs respectively, and rollers adapted for travel in said race in contact with said bearing members and said journal.
